KNIFE AND SCISSORS SHARPENER.

SPECIFICATION forming part of Letters Patent No. 431,887, dated July 8,1890.

Application filed April 8,1890- Serial No. 347,012. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES ALVIN GIL- MAN, of North lVeare, in thecounty of I-Iillsborough, State of New Hampshire, have invented certainnew and useful Improvements in Knife and Scissors Sharpeners, of whichthe following is a description sufiiciently full, clear, and exact toenable any person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whiehFigure 1 is a perspective view of my improved sharpener, and Fig. 2 atop plan View of the same.

Like letters of reference indicate corresponding parts in the differentfigures of the drawin gs.

My invention relates especially to a combin ed knife and scissorssharpener and strop; and it consists in certain novel features,hereinafter fully set forth and claimed, the object being to produce asimpler, cheaper, and more effective device of this character than isnow in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the body of the sharpener, which consistsof a rectangular wooden block, into one side of which and near one end ahandle B is secured, said handle projecting at right angles from saidbody. On the opposite face of the body a strop or finishing -surface Z)is formed. A verticallyarranged standard dis secured centrally in thebody A, the upper end of said standard being forked or spread, formingarms f g. To each of said arms a metallic disk his secured by means ofscrews t'. These disks are arranged in the same vertical plane, andtheir edges are beveled to form cutting-edges. The disks are arranged sothat their edges are in contact, or approximately in contact, as shownat m. A lip 19 projects laterally from the arm g beyond the outer edgeof the disk h.

In the use of my improvement the edge of the knife to be sharpened isinserted between the cutting-disks h and drawn rapidly therethroughwhile in contact with said disks. The blade is thus quickly reduced to asharp edge, which may be finished, as desired, upon the strop l). Thelip 19 serves as a guide upon which to rest the scissors-blade whilebeing sharpened, the cutting-edge of said blade being beveled, and saidlip being arranged at right angles to the disk h. Said disk will reducethe edge of the scissors-blade at the proper bevel when being drawnacross it. By means of the handle B the body A may be held against asuitable support at any desired angle. By loosening the screws 1' thedisks may be turned to present a fresh cutting-surface to act on theknife-blades as frequently as they become dulled.

Having thus explained my invention, what I claim is 1. In aknife-sharpener, a body provided with a handle, a standard mountedthereon, two cutting-disks mounted in the same vertical plane on saidstandard with their edges in contact, and an arm on said standardprojecting beyond the edge of one of said disks, substantially as andfor the purpose set forth.

2. In a knife-sharpener, a rectangular body provided with a handle, astrop on said body, a vertical standard mounted 011 the body andprovided with a laterally-proj ecting arm, and two cutting-disks adjustably clamped on said standard with their edges. approximately incontact, substantially as described.

In a knife-sharpener, the standard (l, pro vided with the lip 19, incombination with the disks h, mounted by screws z' on said standard andprovided with the beveled cutting-edges j, substantially as described.

l. In a knife-sharpener, the body A,provided with the handle B and stropb, in combination with the standard d, mounted on said body and providedwith the lip 13, and the disks h, mounted on said standard and havingthe beveled cutting-edges j, SUlDStELlb tially as and for the purposeset forth.

CHARLES ALVIN GILMAN.
